LCC launches new map of London’s most dangerous junctions, highlighting inaction at ten deadly junctions during Road Safety Week 2025, and one of them is in Clerkenwell…
London Cycling Campaign has updated its Dangerous Junctions mapping, highlighting across London and by borough the most dangerous junctions for cycling, walking and wheeling for Londoners. The new map, launching during Brake’s Road Safety Week 2025, covers five years of emergency services data including newly-released 2024 data.
This year, LCC has also followed up on what happened after ten fatal collisions at ten notorious junctions. Because this isn’t just about kerbs and signals – what friends, family members, TfL and local councils did next, sadly often highlighting the inaction that followed.
That’s why LCC has also launched a new email people can send to the Mayor of London calling on him to be bolder and braver on junctions – to urge him, TfL and London’s councils to act far faster to avoid the next fatal collision at a known and notoriously dangerous junction ever happening.
“All too often the friends and family of those killed at a notorious collision hot spot face a shrug of the shoulders from TfL, the police and our local councils. We shouldn’t have to keep demanding action, protesting, wrestling change from uncaring authorities after yet another cycling fatality. The Mayor of London has committed to ending serious collisions on our roads. It’s time for him to take far bolder measures to do so,” Tom Fyans, Chief Executive, London Cycling Campaign
The toll of lives lost and inaction
Alongside updated mapping, LCC has launched a new petition emailing the Mayor to demand more action from him, the police, TfL and councils and we also have followed up on ten dangerous junctions that have seen fatalities across London.
Each of these fatal collisions have seen families and friends suffer terrible loss. Each of those killed were simply trying to get around London by a largely safe, healthy mode of transport. And in each case, as is all too common, those with most power to take action on these issues – to prevent another fatal or life-ruining serious collision at these locations, known for being danger spots – have failed to do just about anything…
The lesson from these junctions is that with political will, there is a way. Claims we need to ‘balance’ motor traffic, public transport, cycling, walking and wheeling are bogus. If the choice is another life cut short, or many thousands moving through an area safely daily, the Mayor, TfL and London’s councils can choose the latter. The compromises, delays and inaction around too many junctions are currently killing and injuring too many Londoners.
Why aren’t these junctions being fixed faster?
LCC has launched a new email people can send on Dangerous Junctions to the Mayor, calling on him, the police, TfL and councils to act so that every time someone loses their life on London’s streets, walking, wheeling or cycling, the follow-up is coherent, rapid and seeks to remove the causes of such collisions so they don’t happen again. This is what the Mayor has already committed to with his ‘Vision Zero’ for London, a vision his and TfL’s targets show is significantly off track.
Officers in councils across London and even inside TfL have told LCC repeatedly that TfL has itself avoided or delayed changes to many notorious junctions with the primary cause of inaction TfL internally balancing collision number reductions versus impacts to bus journey times. LCC’s view is ‘balancing’ such ideas is ludicrous and lethal given the real problem for bus journey times, that of too many cars, remains largely ignored.
Indeed, TfL could act on both bus journey times and road danger by more boldly separating buses from private motor vehicles using bus ‘priority’ measures, freeing up space and time for walking, cycling and public transport at junctions, by reducing capacity for private motor traffic. That’s what LCC is asking the public to demand from the Mayor today and going forwards.

Updated mapping, new top 10 dangerous junctions
LCC has released its new interactive mapping highlighting the most dangerous junctions in London and each of its boroughs for walking, wheeling and cycling. As before, our map clusters nearby junctions using the latest five years of emergency services Stats19 data, weighting collisions by severity and recency to create a map of the most dangerous junctions for either pedestrians or those cycling, for all of London or by borough.
This new update shows that the most dangerous junction for cycling remains the Upper Tooting Road cluster of ratruns that have seen little to no action from Wandsworth Council or TfL, despite having won this dubious distinction for all three of LCC’s annual updates on dangerous junctions in a row. The last five years data show the junctions around the Ansell Road, Lessingham Avenue and Derinton Road ratruns as they cross Upper Tooting Road are seriously injuring two cyclists a year on average and slightly injuring four more.
The same Cycle SuperHighway CS7 corridor also appears for the third most dangerous junction again at Clapham High Street and Gauden Road (as featured in The Guardian and on GCN recently). And this year, number eight is also on CS7: Balham High Road and Ramsden Road.
The second most dangerous junction for cycling remains the Great Eastern Street/ Curtain Road junction as mentioned above. But new to the top ten are the Cycleway C9 junction of King Street and Weltje Road (number five now) that Hammersmith & Fulham Council has thus far refused to take action on despite a clear pattern of serious collisions from a ratrun from the A4 crossing a bidirectional cycle track.
Also new to the top ten at sixth is the Farringdon Road/ Clerkenwell Road junction, where a “perfect” PhD student was killed in 2024 (the LCC map update now includes 2024 emergency services data) and ninth is the West Hill junction, where Dean Lawson Jones was killed in the same year. Both fatalities having joined existing clusters of serious and slight collisions that meant it was just a matter of ‘when’ rather than ‘if’ a fatality would occur.
For the first time in the mapping, Camden’s actions have pushed one of the two Holborn junctions out of the top ten and the other has dropped several places from five to seven. However, joining the top 10 is Royal College Street / Baynes Street with a pattern of a serious and several slight collisions annually on average.
London’s top 10 most dangerous junctions for cycling, 2025:
- Cycle Superhighway CS7 ‘cluster’ Upper Tooting Road, Wandsworth (around Ansell Road, Derinton Road, Lessingham Avenue)
- Great Eastern Street & Curtain Road, Hackney
- Cycle Superhighway CS7 Clapham High Street & Gauden Road, Lambeth
- Knightsbridge & Sloane Street & Albert Gate, Kensington & Chelsea/ Westminster
- Cycleway C9 King Street & Weltje Road, Hammersmith & Fulham
- Clerkenwell Road & Farrindgon Road, Camden/ Islington
- Southampton Row & Theobald’s Road (Holborn), Camden
- Cycle Superhighway CS7 Balham High Road & Ramsden Road, Wandsworth
- West Hill & Lytton Grove, Wandsworth
- Cycleway C6 Royal College Street & Baynes Street, Camden
LCC’s news blog on the launch also highlights two key emerging trends around the most dangerous junctions: poorer-quality junction designs along Cycleways and older Cycle Superhighways, and missing Low Traffic Neighbourhoods (LTNs).
